Jasper Reports very slow on first call to each report

Started using Jasper Reports (version 5.6.1) and I'm getting a very long delay when calling for the first time a report (around 15 seconds). The other calls execute very fast

JasperFillManager.fillReport("C:/TestReport.jasper", new HashMap<String, Object>());

This is my test report. As you can see it's a very simple report just with a Static Text

</jasperReport>

Any ideas what can be causing this, and how can I solve it?

If I try previewing the report on jaspersoft studio it renders it very fast too.

Solution

  • The problem was due to a corrupted JBoss AS7 installation. After I reinstalled the server everything started working OK.
